This permits to selectively enable explicit congestion notification via the routing table. If this ecn feature is not set, the kernel will use the tcp_ecn sysctl to decide wheter to use ECN when establising a TCP connection. At the time of this writing, the kernel supports ecn and allfrags, but allfrags is of dubious value and not implemented here.
